To all whom it may concern,-

Be it known that I, GUSTAVE ADOLPHE Sonora, asubject of the Queen of Great-Britain, residing at Euston Road, in the county of Middlesex, England, have invented certain new and useful Improvementsin Apparatus or A1)- pliances for the Mixing or Combining of Air and Combustible Vapor in order to render the same suitable for lighting purposes, of which the following is a specification.

According to my invention the apparatus for producing the combustible mixture consists of a metal vessel, preferably of a bottle shape, in the neck of which a stopper may be secured by screwingor otherwise. Through this stopper, and cl ose to oneanother, are passed two metal tubes. The ends projecting at upper part of the stopper are to be connected, respectively, one with an air pump or bellows and the other with atube conveying the air and vapors to the burner or burners of the lamp or lamps. The tubes descend to about one-third of the vessels depth. Over these tubes is fitted another tube, of such diameter and shape as to inclose them, and made of the same length as the others and free to slide up and down, so that when it is pulled up it leaves the orifices of the two tubes free, and when pushed down it makes, like a single orifice, prolongation of the said tubes. The slide-tube is connected by a rod or screw, preferably passing through the stopper to a knob outside the vessel, for the purpose of moving such tube up or down at the will of the operator.

I will illustrate the invention with reference to lamps for medical and microscopical purposes. Figure 1 isa longitudinal vertical section, showing also a sect-ion of the burner, and Fig, 2 is a sectional side elevation of a device or lamp constructed according to my invention.

a is the vessel in which the hydrocarbon is contained. This vessel may be made of any convenient dimensions and form, according to the purposes to which it is to be applied. This vessel is lined with felt or other suitable material, a of an absorbent nature, and held there by a helical spring, as shown. i '5 are the gas-mixing tubes, which, with the necessary plug or cap, 7?, form a stopper to the receptacle, and may be secured to the rim by screwingor otherwise. Through this stopper, and close to one another,are passed the two metal tubes i i.

' The ends projecting at upper part of stopper are to be connected, respectively, one to pipe or tube k, communicating with an air pump or bellows, n, and the other with a tube, Z, conveying the mixed air and vapors to the burner or burners of the lamp or lamps. The tubes 2 i descend'to about one-third or more of the depth of the receptacle-vessel a. Over these tubes is fitted another tube. m, of such diameter and shape as to inclose the tubes i i, and made of the same length as the latter and free to slide up and down over the tubes 5 i, so that when such tube on is pulled up it leaves the orifices of the two tubes 2 13 free, and when pushed down it makes,likeasingle orifice,prolongation of the said tubes. The slide-tube m is connected andactuated by a rod or screw, 0, preferably passing through the stopper i to a knob outside the vessel a, for the purpose of moving it up or down at the will of the operat )r.

The action or operation is as follows: Hydrocarbon-as, for instance, benzolineis admitted in the. chamber a, the supply of which and the level thereof may be regulated by any suitable means. The benzoline may be poured into the holder a to beabsorbed by thefelt, the super fluous benzoline being poured back. The felt will retain sufficient for the supply of the lamp for about anhour. Then, ifthe air pump or bel lows or bag it is worked, a current of air will pass by the tube It and through the tube i and blow on the surface of the liquid in the chamber a, thus evaporating some of it, and the air so mixed with the combustible vapor will flow into and pass away by the tube t" and be conveyed to the lamp or lamps by the tube Z, Now, if the slide-tube m is lowered, a down and up current of air will be formed in it, the upper current ofwhich will partly neutralize the down one, so that a part of the air will be carried away before reaching the surface of the liquid, thus evaporating a less quantity. So the more the slide-tube m islowered less is the quantity of vapor mixed with the air, and

the reverse will take place by pulling it up.

The lamp or burner a is fitted directly onto the pipe Z.

The arrangement of tubes i t" and slide-tube m for regulating the proportions of combustible vapor and air may be applied to a surgical instrument for cauterizing purposes, wherein a platinum tube is used instead of the burner before described.

The burner for producing light by the combustion of the mixture of air and combustible vapors, before described, is formed of a short piece of metal tube, and I fix at one end, preferably at the inner edge, a small cap or chamber of woven platinum wires or other suitable metals or substances, thus forming a combustion-ch amber for, the said mixture. This small chamber may be preferably in the shape of an elongated cone or like a thimble. Over the first cap or chamber I preferably place a second, and over the second a third, about similar in shape to the first, but of larger sizes, so as to leave a small space between them for the purpose of obtaining as perfect as may be combustion of the gas. The second and third chambers are preferably fixed to the outside of the tube.

The working of the burner is as follows: Having previously fixed the burner on the tube l or on aholder or bracket having a tap,

this tap is at first slightly turned on, so as to allow a small quantity ofthe combustible mixture to pass through the burner. Then on the application of a light to the burner the combustion of the mixture takes place, and directly the chambers become red-hot or incandescent. Now, if the tap is turned more on and the slide-tube m is moved up or down according to the proportion of air and combustible vapor required, the chambers will come to a white heat, the result of which is a brilliant light emitted by the incandescence of the metal chambers and a perfect combustion of the vapors. Instead of using woven wire-cloth, finelyperforated surfaces may be used.

I claim as my invention- 1. The vessel a, having an interior lining, a of porous material, for absorbing the hydrocarbon, in combination with an air-inlet pipe, and an outlet-pipe to the burner, and an outer sliding sleeve, with means, substantially as specified, for regulating the position of said sleeve on the outlet-pipe, and thereby regulating the amount of hydrocarbon vapor absorbed by the air, substantially as set forth.

2. The vessel a, having an interior lining, a", of porous material, in combination with the air-inlet pipe i and outlet-pipe t" to the burner, an outer sliding sleeve, m, with regulatingrod 0 attached thereto, a stufiingbox through which the rod 0 passes, and theburner a, consisting of an inner wire-gauze chamber and an outer annular wire-gauze chamber at the end of the pipe t, substantially as set forth.

3. The combination, with the chamber-a, for mixing air with hydrocarbon vapors, ofthe air-inlet pipe i and the carbureted-air outletpipe t alongside each other, and provided with a sliding sleeve m, and with means for adjusting the position of the sleeve m, for the purpose of regulating the amount of absorption of carbureting material, as set forth.
